The guard rail system includes guard rail posts removably secured to a platform member of the scaffolding by inserting a peg into a fixed stop on the platform member, spacing bars for bracing the guard rail posts, and a guard rail supported by the posts. The platform member includes a center channel, and stop members disposed within the channel which are adjustably positioned along the channel. The stop members are disposed on both sides of the planks to maintain the planks in position.
